Patent GB-1196883-A (GB)
Title: Improvements in Apparatus for Paralleling Multi-Phase AC Voltages.
IPC: H02J3/42
Filed: 1969-03-11
Abstract: 1,196,883. Bringing A.C. voltages into parallel. GENERAL ELECTRIC CO. 1] March, 1969 [27 March, 1968], No. 12636/69. Heading H2H. A system for paralleling two sets of multiphase A.C. voltages includes devices for detecting the compatibility of the average voltages, phases, frequencies and phase sequences of the two sets. As shown in Fig. 1, a first source 10 is already connected to a load, and a second source 20 may be introduced by the closure of switches 26 if a signal is present on a line 40 connected to the output of an AND gate 38. The first of three inputs to the gate 38 is provided from a device 28 which determines if the average voltages of the two sets are equal within a preset tolerance. A further device 30 forms two envelopes, each from two phases of the source 20 and the non-corresponding phase of source 10. These envelopes are combined and can satisfy the following circuitry only if the two sources have identical phase sequences. Assuming some frequency difference, the combined envelope will have periodic nodes, and near these nodes the signal will be small enough to indicate to a reference level detector 32 that the instantaneous phases of the voltages are suitable for paralleling. The detector 32 gives, at these times, a second input on line 36 to the gate 38. The time during which the envelope signal is above the reference level gives a measure of the frequency difference between the voltages. As soon as the level is exceeded a signal appears on line 34 instead of line 36, and a timer 48 is started. If the frequencies, are sufficiently close, after a preset time, a signal is sent on a line 46 to set a memory 44 so as to supply a third input to the gate 38. Hence, when next a signal appears on line 36, the gate conditions are satisfied and the switch 26 is operated. If, however, the frequencies are incompatible, a signal appears on line 36 before the timer sends a signal to the memory, and the timer is stopped and reset. The gate 38 therefore does not receive a third input and the switches 26 will be maintained open pending adjustment of the sources.

Title: Improvements in safe load indicators for jib cranes
IPC: B66C23/90
Filed: 1932-05-03
Abstract: 405,653. Jib cranes. BAKER, G., Greno House, Swinton, near Rotherham. May 3, 1932, No. 12744. [Class 78 (iv).] In safety indicating devices in which a loadsensitive member is fitted SO as to move with the luffing gear, the movements of some one part of the load-indicating mechanism due respectively to changes in load and to changes in the inclination of the jib are transmitted to an indicator on a fixed part of the crane through mechanism such that the indicator shows whether the load is less than, equal to, or greater than safe load at any radius. The indicator may also show the actual proportion of safe load carried by the crane, through a limited range near the safe load. As shown in Fig. 1, the sheave P of the luffing gear is mounted on the mast so that the pull in the luffing rope is transmitted through the spring A, and the pin E, Fig. 2, moves in the stirrup B, in proportion to this pull. In luffing, the stirrup B moves about the axis C, but the pin E is connected by a link G to a radius rod R pivoted at S, and the movement of the pin H connecting the members G and R is transmitted to the indicator as by a member W. Fig. 1. The appropriate path of movement of the pin H is determined graphically, as described with reference to Fig. 4 (not shown). The necessary constraint may be provided by a lever such as R, or by guides, or by a combination of levers and guides. In Figs. 5-7 (not shown), the lever R is formed as a bell-crank, and the movement of a point of the bell-crank not coincident with the pin H is transmitted to the indicator. In Fig. 8 (not shown), the link G is connected with pin E through a transverse lever which multiplies the movement due to the load. The link G may be attached directly or through levers to any other part of the mechanism which moves under load and also moves about the axis C in luffing. In two constructions shown in Figs. 9 and 10, the link G is replaced by a cam T pivoted at S, engaged by the roller E, and connected to the indicator by a rod W ; the method of determining the contour of the cam and the position of the pivot S is described. The indicator, as shown in Fig. 1, moves over a plate Y marked " Safe," " Caution," and " Danger," the part marked " Caution " indicating that the load exceeds three-fourths of the safe load. The pin H may operate an audible signal when the load is equal to maximum safe loads at any radius. Specification 386,655 is referred to.

Title: Improvements in or relating to combined voltage regulator and magnetic cut-out circuits
IPC: H02J7/02
Filed: 1932-05-03
Abstract: 400,679. Automatic electromagnetic regulators ; variable-speed generator systems ; charging and discharging batteries. LOCK, A. C. and SIMMS MOTOR UNITS, Ltd., Percy Buildings, Gresse Street, London. May 3, 1932, No. 12769. [Class 38 (iv).] In a circuit, such as a battery-charging circuit, including both a voltage regulator and an electromagnetic cut-out, the operating coils a, b of both these devices are compensated for temperature changes by a single swamping resistance c, which has a negligible temperature coefficient of resistance. Sections t, t1, t2 of the swamping resistance may be short-circuited by switches d, d1, d2 to alter the operating voltage of both regulator and cut-out simultaneously, the connection, such as e, e1, e2 being also altered so as to vary the number of cells to be charged. Alternatively a selector switch may operate on tappings on the resistance so as to cut-out or short-circuit steps of resistance.

Title: Purification of beta-lactones
Filed: 1959-04-15
Abstract: b -Lactones of aliphatic acids contaminated with aliphatic carboxylic anhydrides, such as are obtained by the reaction of ketene and a carbonyl compound, are purified by hydrolysing the anhydride to the corresponding acid with water added in amount at least stoichiometrically equivalent to the anhydride present and distilling, the hydrolysis being effected partly or wholly before or during the distillation and at a pH not above 7, and recovering lactone separately from aliphatic acid and from higher boiling substances present.  The process may be effected in a column from which water and aliphatic acid are removed overhead and the higher boilers discharged at or near the bottom, the lactone being introduced at an intermediate point and the water at the same or another intermediate point, and the purified lactone taken off in vapour form from a point below the point(s) at which the lactone and water are introduced.  A mixture of crude lactone and water may be heated to effect hydrolysis of at least part of the anhydride before being introduced into the column. The process is applied to the purification of b -propiolactone.  The higher-boiling bottoms may be reacted with alcohols in the presence of a dehydrating catalyst to give esters of a ,b -unsaturated monocarboxylic acids, methyl acrylate being thus prepared using a NaH2PO4/H3PO4 mixture.
